| Abstract: | LiFePO4/C has been regarded as one of the most promising cathode material for power lithium-ion batteries due to its attractive properties，such as remarkable thermal stability，low cost，excellent cycling performance，and environmental be-nignity.Therefore，it attracted a lot of attentions in the lithium-ion battery industry.But the development of this cathode mate-rial was constrained by its low electrical conductivity and slow diffusion rate of Li+.The crystal structure，performance，princi-ple of charging and discharging，and doping mechanism were also introduced.Especially，the research progress in doping modification of the LiFePO4/C materials in recent years was reviewed. |
